Application filed September B, 1917. Serial No. 190,370.

To allvwlwm z't may concern.' Be it known that ll, AsHELL WILLARD BARNUM, a citizen of the United States, re-

' character which will enable the head of a pick to be securely fastened upon the handle so that there will be no danger 'of the pick `becoming yaccidentally disengaged from the handle when in use.

Further objects lof the invention are to provide a device of this character which' is comparatively simple and inexpensive in its i construction, which can be readily placed in position or removed therefrom, which will hold the head of a pick securely in position upon the handle, and which will shield and protect those portions of the handle adjacent the head of the pick in such a manner as to greatly prolong the life ofthe handle.

,With these and other objects in view, the invention consists in certain novel combinations and arrangements of the parts as will more fully appear as the description proceeds, the novel features thereof being pointi ed outin the appended claims.

For a fullulnderstanding of the invention, reference is to be had tothe following description and accompanying drawing, in whichz Figure l is a side elevation of a pick provided with a handle fastening means constructed in accordance with the invention.

Fig. 2 is a top plan view .of the same.

Fig. 3 isa detail perspective view of one of the sheet metal retaining st ips, portionsbeing broken away and shov n in section. l

Fig. 4ty is an enlarged transverse sectional view on the line 4-4 of Fig. l.

Corresponding and'like parts are referred to in the following description and indicated in all the 'views of the drawings -by the saine reference characters. 4

. Referring to the drawings, which illustrate one possible embodiment of theifnvcntion, the numeral 1 designates/" woden pick handle, and 2'Va pick head which is socketed at the middle thereof forAthe rece tion of the'pick handle. The handle 1 is preferably elliptical in cross section, asindicated niore clearly by Fig. 4l, and a pair of longitudinally extending retaining strips 3 and 4 applied to the edge portions of the handle at that end thereof which is engaged by the piek head 2. rlfhese retaining plates 3 -and 4' are curved transversely to correspond to the contour of thepick handle and` fit snugly against the same, said strips extending through the socket of the pick head and each terminating at its outer end in a pair of laterally projecting wings 5 which engage the front of the piek head. The..

back of lthe pick head is engaged by spring v shoulders 6 which are formed by stamping tongues in intermediate portions of the retaining strips and curving them outwardly. The retaining strip 4 may be formed with teeth `7 arranged to bite into the handle 1,a pair of opposed. straps 8 being provided at the rear end' of the retaining strip, said straps extending around the handle and other retaining strip-3 and `terminating at the top of the pick handle in ears 8a which are connected by'a 'clamping bolt 9. When this bolt is tightened the-straps 8 are drawn tightly' around the pick handle and strip 3, thereby clamping the parts firmly in position and causing the teeth 7 of the strip 4f to bite into the handle.

These straps 8 are formed with longitudinally extending slots 10 which receive out standing lugs .l1 p llojecting lateral] from the edges of the`stripV4 3. An inter ocking connection is thus produced between the two retaining strips 3 and 4 which prevents either of them from moving independently of the l other when they are assembled in operative and the clamping and spring the inner endsof the stri s 3 and 4c apart suciently to ,disengage the woodenfhandle, whereveeth 7 from the The teeth 7 of the strip.

tie

, are merely reversed. When the. piek head is in 'position it held in such a manner that; it cannot become accidentally disengaged -t'rom the piek handle. and the strips 3 and t serve as shields for those portions of the handle operated adjacent to the piek head,

thereby preventing thehandle from being splintered or shattered by benig brought repeatedly into contact with the material or.

objects upon which the piek is being employed. lt desired, one of the members may be provided. witlra perforation l2 for the purpose of enabling a tag to be readilvv attat-hed to the pick when itis sent to the shop for sharpening or repairs. lQaeh worln'nan will thus be enabled to have his proper pick lreturned to him without any delay or contusion. p

Having thusdescribed the invention, what l' elaim as new and desire to secure' by Letters Pate1it,is:

l. The combination with' ay socketed tool head and ay handle insertible within the socket,of longitudinally extending retaining strips applied to opposite sides of the handle and extending through the socket of' the tool head, said strips being provided at `their outer` extremities with lateral wings which engage the front of the tool head and one ol the strips bein provided at its inncr'end portion with teet adapted to bite vinto the handle and also with opposed4 straps arranged to extend around the handle and other strip,v and a clamping bolt connecting the ends of the straps.

2. The' combination with ,a socketed tool head and a handle insertible. within the socket, 0f longitudinally extending retaining strips applied to opposite sides of the handle and extending through the socket; of

lthe tool head, said retaining strips terminating at their outer extremities in lateral wings whieh engage the front ot the tool head and the inner end portion ot one of the strips being provided with lateral `lugs while the inner end portion of the other strip is provided with teeth adapted to bite into the handle and also with complementa] straps adapted to extend around the handle and first mentioned strip, said lstraps being slotted to receive the lugs ol' the iirst mentioned strip, and a clamping bolt connecting the ends ot the straps.

3. The combination with a sorketed tool head and a handle insertible through the socket, of longitudinallyextending retaining strips applied to opposite sidcsof the handle and extending through the socket of the tool head, the outer ends ot' the strips terminating inlateral wings which engage the front of the tool head while intermediate portions ot' the strips are provided with shoulders for engagement with the bark oi' the tool head, the inner e'nd portion of one strip being provided with lateral lugs' and the inner end portion ot the other strip bcing provided with teeth adapted to bite into the handle and alsoswith eomplemental strap members arranged to extend around the handle and first mentioned strip, said strap members being slotted to receive the lugs of the firstmentioned strip, and a olan'iping' bolt connecting the ends of the strap members.- y
